I should have posted this earlier, but we've got a really nice garden tour today in northern York County, (Biddeford, Saco, and Biddeford Pool) 9am to 3pm. We pride ourselves on featuring "working" gardens, where the homeowner does the work, the gardens are not professionally landscaped. 10 really inspiring gardens.
Tickets on sale this morning til noon or so at the Dyer Library, 371 Main St. (Rt. 1). The weather's great!
